SHUT-OFF DEVICE} QR V ALVE FOR CARIBURETERS.

Specification of Letters la'tent. PatentedFeb, 11,1913,

Application filed April 15, 1912. Serial No. 690,964.

To all whom it may concern.

citizen of the United States, residing at West New York, in the countyof Hudson and State of- New Jersey,.have invented certain new and usefulImprovements in Shut- Off Devices or Valves for Carbureters, of whichthe, following is a specification.

My invention relates to shut-ofi' devices or valves for carburetors.

It is absolutely necessary to have the carbureter valve of an. internalcombustion engine as near as possible to the carbureter, so that whenthe valve is shut off the feeding of gasolene to the carbureter willstop immediately, but on account of the valve being close to theCarlo-ureter, if the carbureter is set on fire from a back-fire from theengine, which often happens, the automobile or launch in which theengine is installed is set on fire and damaged or entirely destroyed, asit is impossible to shut off the valve manually without being burnt.

My invention therefore has for its object to obviate the above result ofa carbureter being set on fire by providing a shut-oft device embodyingremovably applied means which is readily fusible or destructible by fireand adapted to hold the valve open and means adapted to automaticallyclose the valve when it is released through the de struction of theholding means by the fire from the burning carburetor, or when it isreleased by the manual removal of the holding means. i I

It has for a further object to provide means of the character and forthe purpose above set forth which embodies advantages in point of simpleand inexpensive construction and eifective operatic In the drawings:Figure 1 is a fragmentary view of an automobile. showing the valve towhich my invention is to be applied. Fig. 2, a plan view of my inventionapplied to a valve. Fig. 8, an end view thereof. Fig. 4, a plan view ofthe holding plate. Fig. 5, a side view of one of the pins.

For the purpose of showing the location of the valve to which myinvention is to be applied, I have illustrated it in Fig. 1 of thedrawings, forming a part of this application, in connection with theparts of an automobile directly associated therewith.

Referring to the drawings in which like reference characters designatecorresponding parts, 1 designates the frame or chamis of an automobileon the front of which is mounted an internal combustion engine havingthe usual crank and gear casing 2,- cylinders 3, manifold 4 connectingthe cylinders, pipe 5 connecting the water jackets of the cylinders withthe radiator, not shown,

and fly-wheel 6 of the engine crank shaft and on the back of the frameor chassis of the automobile is mounted the usial oil tank .7.

A carb ureter 8 of the usual construction is mounted at one side of theengine and connected with the manifold by a branch pipe 9 thereof andthe carbureter is connected with the oil tank by a pipe 10 through whichoil is fed to the carburetor.

The pipe 10 is provided adjacent the carbureter, preferably directlyunder it, with a valve casing 11 having lateral lugs 12 and 13, the endsof which are provided with pins Hand 15 respectively grooved at theirouter ends.

A tapered valve 16 is provided in the casing, one end of the valvehaving a laterally extending handle 17 provided with a pin 18, groovedat its outer end and the other end of the valve having a reduced portion19 extending beyond the casing and provided with a spiral spring 20located between washers 21, the outer washer bearing against a pin 22which holds it in place.

The valve is held in its open position, shown in full lines in Figs. 2and 3 of the drawings, by means of a plate 23 of material readilyfusible or destructible by fire, preferably bismuth, the plate beingheld removably in placeby means of a hole 24 therein engaging the pin 15of the lug 13 and a hole 25 therein engaging the pin 18.

The valve 1s automatically closed spirit and scope. of my invention andimprovements. I therefore reserve the right to all such variations andmodifications as properly fall within the scope of my'invention andclaims. 3

I claim a a 1. Ina device of the character set forth, a casing havinglugs, a valve in said casing, means readily destructible by fire securedat one end to the valve and at the other end to one of the lugs of thevalve casing and normally holding the valve open and re- 2. In adevice-of the character set forth,

a casing having lugs, a valve in said casing,

the terms of the 7 following casing and normally holding the valve opendetachable mean's readily destructible by fire secured at one end't'othe valve and at the other end 'to one of the lugs of the valve andresilient extensible and retractible means secured at one end to thevalve and at the other end to the other lug of the valve casing andadapted to automatically close "the.valve when the valve is releasedfrom the holding means, substantially as described.

. In testimony whereof I have signed my name in the presence of twosubscribing witnesses.
